our reporter pam brown has been there. she's in watertown, back with us live and most of that area, it looks like a ghost town behind you. it's locked down. >> reporter: it really is. it's desolate around here. i was just thinking it feels like it would maybe on a big holiday. all the stores are closed. you don't see any residents walking around, no cars on the streets other than the o'occasional humvees and state police cars that drive by us. so it really is a ghost town. to my right, not far from where i am, there was a situation where authorities had their guns drawn, and they were surrounding someone. we just learned moments ago that that scene has been cleared, that they don't believe the person they were surrounding was the suspect we're looking for. this situation here in watertown continues to escalate as authorities look for dzhokhar tsamaev. the entire area on lockdown. hundreds of thousands of people in their homes. the doors locked as this man hunt continues. >> all right pam brown. thank you for that latest up
